Good morning, my dear classmates

I'm very glad to have this chance to talk to you. The topic of my speech is Let's ride a bicycle.

As is known to all, with the improvement of people's living standards, cars have become a popular means of transport, bringing great convenience to our life. However, they have also caused some problems such as air pollution and traffic jams.

How can we solve these problems then? As far as I'm concerned, riding bicycles is a good solution. For one thing, bicycles don't need any petrol and they are energy-saving. For another, bicycles are environmentally friendly because they won't give off waste gas. What's more, riding bicycles is a good way for us to exercise and it is beneficial to our health.

Therefore, let's take the responsibility to build up a low-carbon city by riding bicycles. Come on and join us!

Thank you for listening!

亲爱的同学们：你们好！

我很有机会在这里和你们。我今天演讲的题目是：“让我们骑车吧！”

众所周知，随着人们生活水平的不断提高，小汽车已经成为了流行的交通工具，它给我们的生活带来了极大的便利。然而，小汽车也同时引起了污染和交通拥堵的问题。

那么，我们该如何解决这些问题呢？ 我个人的看法是，骑自行车就是一个很好的解决办法。一方面，自行车不需要汽油，这就节省了能源。 另一方面，由于自行车不会释放废气，因此，他们是环保的。再者，对我们来说，骑车是一种很好的锻炼方式，这对我们的健康非常有利。

因此，让我们通过骑自行车，承担起建设低碳城市的责任。加油！行动起来吧！

谢谢倾听！
